- IMPROVEMENT IN LAWN-MOWERS.

Specification forming part of Letters Patent No. 126,102, dated April23, 1872.

To all whom it may concern:

Be it known that I, GEORGE W. Trsoruza, of Dayton, in the county ofMontgomery and State of Ohio, have invented a new and valuableImprovement in Lawn-Mowers; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makinga part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawing is a representation of a top-plan view of myinvention. Figs. 2 and 3 are detailed views of the same.

This invention has relation to lawn-mowers; and consists in the novelconstruction and arrangement of devices'for making the machine moreeffective in operation, all as hereinafter described.

In the accompanying drawing, Arepresents a rectangular frame, supportedin front by two small side wheels, to, and in the rear by thedriving-roller B. Upon the shaft of said roller is placed a loosespur-wheel, G, from the inner face of which projects a clutch-block, D,which fits another clutch-block, D. The clutchblock D is arranged toslide'alon g the shaft, and by means of key-and-groove fastening is madeto turn with it. The teeth of the clutchblocks are beveled, so that saidblocks will work together as the roller moves forward. A forkedspring-bar, E, or yoke attached to the rear end of the frame A, servesto keep the clutch-block in position. This block may at any time bedetached from its mate by means of a pin, (1, passing through the sideof the frame A'and touching the bar E. The spurwheel 0 engages with apinion, e,on the shaft of which is a beveled tooth-wheel, F, engagin gwith a pinion, f, on the inner end of a horizontal shaft, G, which isjournaled to the side of the frame A. H designates a crank-plate orwheel on the outer end of said shaft; H, a pitman conecting said crankto the cutter-bar h. I is a bar hinged to the shaft G, and also to thefinger-bar K. A slotted standard, L, is attached to said bar I, andrenders the bar I and finger-bar adjustable, a pin, 2', being used tohold the standard L at any desirable point.

M represents the handle by which the lawnmower is propelled. This handleis pivoted to one side of the frame, and has attached to it a slottedstandard, N, which renders said handle adjustable. The pin a fastens thestandardN to the frame. The standard may be removed when desired, andthe handle thrown forward and used in pulling the mower.

What I claim as my invention, and desire to secure by Letters Patent,is-

A lawn-mower, constructed substantially as described, consisting of theframe A, drivingroller B, wheels 0 e F f, clutches D D, shaft G,crank-wheel H, pitman H, and cutter-bar h, with the spring E and pin d,substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
